Problems solved by technology
But the disadvantage of this method is that the image needs to be precisely focused on the translucent display screen, and the focal length of the projector needs to be adjusted manually, which increases unnecessary maintenance costs
Another shortcoming is that the size of this rear-projection copying device is relatively large, and it is difficult to carry
Another shortcoming of the existing equipment is that it is not possible to adjust and control the selection and size of the copying font by touch

Embodiment Construction
[0044] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0045] like Figure 1A As shown in, in order to facilitate copying and learning calligraphy, the present invention provides a display device suitable for copying. By displaying calligraphy works 120 on the conventional display device 10 and then covering the rice paper on the said device and copying, it is found that the edge of the copybook 122 through the rice paper 11 is very fuzzy (as Figure 1B ), because the detailed structure of copybook cannot be seen clearly, so such conventional display is not suitable for calligraphy copying. In addition, since copybooks need to be selected and resized when copying on the screen of the display device, the display device is required to have a touch function to facilitate the operation of the content displayed on the screen. And when copying on the display device screen, the display device screen is in the ho...

The invention provides a display device which is characterized in that the display device comprises a display screen, wherein the display screen comprises a display layer and a protective layer which covers the display layer; when the display screen displays a black image and a white background and furthermore paper is laid on the external surface of the display screen, an image which is presented through the paper is compared with the image that is displayed on the display layer, and the fuzzy width at the edge of the image which is presented through the paper is smaller than 3mm, wherein the fuzzy width of the edge of the image which is presented through the paper from the black image to the white background. The invention further provides a digital desk in which the display device is embedded, wherein a copybook for copying is displayed on the display device. The copybook displayed on the display device can clearly penetrate through rice paper, thereby facilitating copying.
Description
technical field [0001] The present application relates to the field of display technology, in particular to a display device and a digital desk. Background technique [0002] At present, the existing copying learning devices for calligraphy and painting are mainly to print the original manuscript into paper products, and let the learners carry out "trace red" copying, or place the copying objects such as the original printing or printed paper products on the LED Copying is carried out above the light source lighting equipment, and the copying objects are static prints, which cannot realize dynamic copying, which is not conducive to users' effective learning of calligraphy or painting methods. Secondly, currently existing calligraphy and painting imitation learning devices with dynamic display functions usually adopt the method of rear projection to project the imitated fonts onto a translucent display screen, and display the imitated fonts on the translucent display screen. ...
